This paper examines the effects of the mean target speed on the synthetic aperture radar (SAR) imagery morphology of signatures induced by surface movers that are transitioning from a lower to higher speed during the collection interval. The radar platform moves with a constant velocity on a level flight path for the case of a broadside imaging geometry. Recent studies have revealed that such moving target smears are not constrained to have the simple shapes of mere parabolas but instead can display a rich variety of two-dimensional (2D) shapes, including self-crossing signatures. The current analysis investigates the properties of the theoretical 2D central contours of these smears under the conditions of varying the mean target speed for targets which transition from lower to higher speed. It is shown that these theoretical predictions of the signature contour morphology yield excellent agreement with the results of SAR image formation applied to simulated radar data.
